I M .8 ATTO NEYS Patented July 12, 1932 UNITED STATES PATENT/OFFICERICHARD LANGE, F LEONIA, NEW JERSEY METHOD OF AFFIXING STAMPING MATERIALTO BOOK COVERS AND THE LIKE W i Application filed. May 24, 1930.SerialNo. 455,299.

This invention relates to an improved method of applying and aflixing astamping medium such as roll leaf, bronze composition, and the like, tobook covers or cases and similar articles and has for its object theproduction of amore expeditious mode of treatment for applying andaflixing stamping medium to book covers and other articles to p be thusembellished, stamped or printed.

l A further object includes a mode of treatment for stamping andembellishing book covers, and the like, whereby the stamping material isapplied and ailixed by a series of continuous, successive steps in sucha manner as to give the complete product a clean cut outline andsuperior finish.

It is further my purpose to apply the roll leaf or equivalent stampingand embellishing material to the book covers or other arti- 0 cles to bestamped, embellished or printed in stages, that is to say, the stampingmaterial is first applied to the book cover with just sufficientpressure and under suitable conditions a of temperature to fully attachthe medium onto the surface of the book cover or other article. Thisstep may be performed by use of a suitable die, plate or printingcharacters operated by suitable mechanism, or by hand, and withsuficient pressure to thereby attach the stamping medium to the surfaceof the book cover without depressing the material into the surface atall or only slightly. I

then separate the dieor other stamping unit from the applied stampingmaterial and brush or otherwise clean the stamping unit.

The cleaning may be done in any desired manner, as by moving saidstamping unit away from the stamping material and over a brush,

or by brushing the same so as to obtain a clean in surface for the nextstep of impressing the stamping. This step is applied under suchconditions as will impress or embed and affix the stamping material intothesurface of the book cover and integrally unite the same with thesurface and at the same time burnishing the stamping material thusunited. For convenience this step may be'called the afiixing step and issubstantially as follows:

The book cover or equivalent and the clean stamping unit are advancedlaterally The several steps may and brought together in relatively thesame position as was had when the stamping medium was attached to thesurface of the book cover. The book cover is preferably moved from thestamp applying position to the 65 stamp aflixing position and thestamping unit is similarly moved to the new position so that thestamping unit registers perfectly with the original stamping impression.Pressure is now supplied to the book cover and stamping unit; that is,these elements are brought together under suitable conditions ofpressure and temperature to impress the stamping material into thesurface of the book cover or other article and at the same time burnishthe stamping. The contact between the stamping unit and. embellishedsurface is then broken by withdrawing either the book cover or thestamping unit, or both. i

The next step comprises cleaning the impressed cover so as to remove anysuperfluous stamping medium. This may be done by brushing (under avacuum if desired) the stamped surface so as to remove all loose 7particles of stamping material from the book cover. The next stepembraces the applica-' tion of a protective coating material such as asolution of collodion which may be applied in a suitable manner such as'spraying, brushing, or the like. It is my purpose to cover theembellished ortion as wellfas the book'cover itself to tl ius fullyprotect the cover and the embellished portion. After spraying thecoating is dried and the book cover is ready for use. The articlethusproduced has a clean, clear cut outline, a superior finish and willwithstand wear and tear for a long eriod of time.

be summarized as follows:

1. Supplying and applying the book covers.

2. Applying or laying on the stamping medium such as metallic leaf. I i

3. Cleaning or brushing the leaf applying means.

4. Impressing, that is, aflixing .and burnishing the applied stampingmedium.

Removing free stamping mediumLv sion book covers is used in a genericsense and that the process or mode oftreatment is applicable to otherarticlesor surfaces that may bemthus treated. I a 7 Referring now to thedrawing:

Figure 1 shows means for supplying book covers and represents the stepof laying on or applying the stamping medium; I

Fig.2 represents the die cleaning step and the step of impressing andburnishing the applied stamping medium;

V Fig. 3 shows the. successivesteps of removing free stamping mediumfrom the cover, also of applying a protective coating medium to the bookcover and of drying the same.

If book covers are to be treated then these may be supplied by anysuitable means as, for example, from a stack 10 by a suction device 11which picks up the book cover and deposits it on a conveyor 12. The bookcover 13 is then placed in position on the printing bed 14 immediatelybeneath the die or printing unit 15 which is slidably held in the heatedhead 16. A'strip of stamping'medium 17 is held between the book coverand the die so that the same will be brought into contact with the bookcover when the impress is made. In the first position the impress is butlightly made so as to lay on the'stamping material or, at most,impressing itbut very slightly. These two stages are shown in Fig. 1where 13 represents the book cover with the stamping medium 17" placedthereon lightly, while 13 represents the book cover with the stampingmedium 1'7 slightly im pressed. The next step in the successive processrequires the removing of loose stamping medium from the printing unit;This is ac complished by any suitable means such as a brush 18 overwhich the printing unit is caused to slide into the affixing position inwhich position the step of afiixing or impressing and burnishing isaccomplished.

The impressing and burnishing step is accomplished by applying theprinting unit onto the stamping medium-in the exact relativepositionthat it had when the first impress was made. That is to say, theprinting unit and the cover to which the stamping is now attached, areboth moved to the impressing position and then brought together insubstantially their exact relative position and pressure is applied atsuitable temperature to impress the stamping material into the surfaceof the cover as is shown at 17 and 13. The stamping is burnished atthrough the drying step Thefdi' ying may be accomplished by any suitablemanner as by a rack 20 which picks up the books and delivers themto thebottom of a stack 21. It

will be seen from the above that the severallike articles withastampingmedium which is properly vfixed and burnished as well asprotected and which has clean, clear cut ed es and superior finis'h. Itis obvious that ot er instrumentalities may be employed for carry ingout the several 'steps'above described.

I claim: i I

1. The method of applying and affixing a stamping medium to a book coverand like article, which comprises affixing, a stamping medium to thesurface of a book cover, then moving said cover and stamping and againimpressing the affixed stamping medium into thesurface of the book coverand burnishing the same, then cleaning said cover, then a plying aprotective coating material-and drya ing said coating material. 7

' '2." That method of applying andafiixing roll leaf to book covers andthe like which comprises attaching said roll leaf to the. surface of abook cover with sufficient pressure to cause the roll leaf to adhere tothecover, then shifting the book cover and stamping and impressing saidroll leaf into the surface ofthe book cover and burnishing the same,then removing thesurplus' of roll leaf from thecover, then applying acoating material to the impressed surface and book cover, and finallydrying the coating. A

3. That method of applying and aflixing roll leaf to book covers andthelike,- Which the same.

j4.,-,That method'of applyingand affixing a stamping medium to bookcovers and like articles, which comprises supplying book covers inarranged order, then applying a stamping medium to the surface of thesue cessive book covers, then moving the book covers laterally to newposition and again applying pressure to the applied stamping medium soas to impress the same into the surface and burnish at the same time,then removing free stamping medium, then applying a protective coatingand drying the same.

5. The step of applying and afixing stamping medium to book covers andlike articles, which comprises impressing stamping medium lightly ontothe surface of a book cover or other article, then cleaning theimpressing means and again applying said means to the stamping mediumfrom a different posi-- tion in the same plane with increased pressureto impress the stamping medium into the surface and burnish the same.

6. That method of applying and affixing stamping material to an articlein stages which comprises applying the stamping lightly in the firststage, then moving the stamping laterally and removing loose stampingparticles and impressing the applied stamping into the surface of thearticle.

7. That method of applying and aflixing stamping material to an articlewhich comprises applying said stamping material with sufficient pressureto attach the same to the article, then moving said article and cleaningthe stamping means and again applying the same with increased pressuretosaid article for the purpose of permanently affixing and impressing saidstamping material into the surface of the article, then cleaning thearticle and coating the same.

8. That method of applying and aflixing stamping material in stages toan article to be stamped or ornamented which comprises attaching thestamping material to the article, then moving the stamp applying meansand article to new positions and again applying pressure so as to affixthe stamping material and then brushing.

9. That method of applying and afiixing stamping material to an articleWhich comprises supplying and registering said article, then laying onthe stamping material on the article to attach the same thereto, thenmoving the article and stamp aflixing means laterally and brushing thestamp applying means and again impressing said stamping material,burnishing the same.

In testimony whereof I have hereunto set my hand on this 16th day ofMay, A. D. 1930.
